Increase in Ultimate Load and Yield Load of Beam Column Joint after Retrofitting

Reinforced concrete structures may be required to be upgraded for various reasons like structural inadequacy of materials (concrete and steel), deterioration of materials, initial deficiencies in design or construction, poor and improper maintenance, unexpected loads not considered in design initially and revisions in design codes and practices . The use of FRP to repair and rehabilitate damaged steel and concrete structures has become increasingly attractive due to the well known good mechanical properties of this material. Strength, stiffness and ductility of few elements or whole building can be altered by retrofitting. Ferrocement jacketing is a technique of retrofitting which can be useful as it is economical, easy to apply from view point of less skill labour requirement, lightweight and high tensile strength. In this study for shear lacking RC beam- column joints, deflections and loads of specimens were noted down after stressing the specimens to ultimate load and load levels lesser then ultimate loads. Then retrofitting was done with ferrocement jacket and and specimens were tested again. Resultant Strength and other parameters were compared to control specimens. Increase in load carrying capacity was observed as a result of retrofitting. Yield load was also observed to increase
